Ubuntu 20.04 not recognizing keyboard

After updating to version 20.04, the keyboard doesn't work anymore. I read in some other answers to use an external keyboard, but this is exactly what I am doing. I tried to boot with a old kernel, but I couldn't because when booting I hold the SHIFT button but it is not recognized.

In order to answer this question with any sort of accuracy, it will be helpful to know the brand and model of your computer. If this is a desktop machine, knowing the model number of the keyboard could also be useful. With specific questions come specific answers

AX68002 corresponds to KVM 2 ports USB. https://www.plantautomation-technology.com/products/asix-electronics-corporation/2-port-usb-kvm-switch-soc-ax68002 What is the output of executing **lsusb** ?

@Deffo Thanks. In my system I see perfectly clear the Keyboard: ```Bus 001 Device 004: ID 046d:c31c Logitech, Inc. Keyboard K120``` Can you try connecting another keyboard?. Some times drivers fail. Something to try too, is to plug the keyboard to another port.

@CarlesMateo already tried changing keyboard and changing...none of these worked

Any messages if you do ```dmesg -T | grep -i "keyboard"``` ?

I am not an expert but ran into the same problem, used Tasksel to remove a package [BIG NO NO NOO!] and it removed lots of other packages and caused all USB ports to stop working. I sadly had to reinstall cause the system was very damaged. If you can look at what packages you have removed or the installation process removed and see if anything looks suspicious.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
